Bernie Sanders and Elizabeth Warren accuse Amazon of ‘potentially illegal’ activity in new attack against the company’s labor practices

The pair has drafted an official letter to Amazon, inquiring about a video about union activity that is reportedly being shown to Whole Foods managers, according to the Washington Post.

“We write to express our alarm at recent reports that your company is distributing anti-union materials to Whole Foods managers that directs and encourages potentially illegal interference with the rights of thousands of workers,” Sanders and Warren wrote in the letter, the Post reports.

The senators are demanding a copy of the video and details about how it is distributed and to whom.

The video laid out the consequences that the company would suffer if employees attempted to form a union.

“We do not believe unions are in the best interest of our customers, our shareholders, or most importantly, our associates,” a voiceover says in the cartoon video. “When we lose sight of those critical focus areas we jeopardize everyone’s job security: yours, mine, and the associates.”

“We have received the letter from Senator Sanders and Senator Warren, and will be responding to them directly,” an Amazon spokesperson said in a statement to Business Insider.

They continued: “Amazon respects the individual rights of employees and has an open-door policy that encourages employees to bring their comments, questions, and concerns directly to their management team. We firmly believe this direct connection is the most effective way to understand and respond to the needs of our workforce.”

“It is important to recognize that workers’ rights do not stop at the minimum wage, and raising the pay of your lowest-paid workers, while important, does not give you a free pass to engage in potentially illegal anti-union behavior,” the letter reads.
